A10 cal data in true or complementary form rom` the same keys or controlling members which may be marked `with thev true form of the data so 4that complementsmay be Aentered without mental calculation on the part of the operator. ,i t Y' The-invention` is particularly vadapted Lto punchingtabulator cardsand is applicable either tov single'hole or multiple hole systems but for the sake of simplicity .'will be disclosed in connection with a single hole system. A well known punching machine for pertorating so-called single hole or Hollerith cards consists of Aa row of punches 'beneath which the columns of are'cord vcard areY fed successively. The card is stopped with the several columns beneath Vthe punches and the keys or controlling members are operated `to effect operation of one punch for each column,

the particular punch selected liXing the posi- 4 30 tion of the perforation, which position in turn Xes the meaning of the perforation inthe card. The Hollerith cards usually deal with numerical data and each column is divided into ten partsl representing by their position the ten digits generally designated as index pointpositions. A single operating member or keyis provided for each punch and normallythe operation of a key results in a punching operation by a selected punch. Ac-

40 cording to the present invention additional selecting mechanism is provided so that each key may select either its corresponding punch or another selected punch inthe series. l This is particularly useful inpunching tabulating cards to be used in subtracting operations. It is common practice in automatic accounting machines to effect subtraction by adding positive' items in 'their true' values and negative vitems in 4"their :complementary values whereupon l'the accumulators 4or zcounters `in which each. key selects the `punch l.corre- 287,018,'a11d in Germany March 16, 11928'.v

show the balance between .the positive and negative items. The complementary` value of negative items necessary for subtractionfin lthe decimal system is ythe true or tensl complement of the items. In tabulating practice 355 vthe tabulating cards may be punched with the tens complement of the ligure the units Y Y.

order'of a number. and the ninecomplements of figures in the other denominational orders or-all ligures yof a number may bejpunched as nineVv complements y and the additional unit necessary m the umts denominational. order entered through automatic operation ofthe tabulator. Both systems arein use aridwelll known n automatic accounting ,machinef practice. l E" f l `In the present'case a credit item' is punched -bythemachine in itsusual condition result' ing in perforations corresponding vto the op"V eratin'g key or members.l A'shifti-ng mecha` Lf nism is provided which disarranges thenormal .relationship between the keysf and Ypunches and substitutesanother relationship sponding to its complementary value. In the usual, subtracting operations the nine complements are used in Whichcase the key or operating member designated 1 `would selectively control the punch representing lor the 4 punch representing 8., the other keys or oper- 280 ating members operating inlike manner.'- The invention is illustrated yby way of eX- ample in the accompanying drawings in which, i Y A Fig. l is a plan view of a well known formyet key punch Vembodying the invention;

`Fig. 3 is an enlarged detail of theV punch mechanism in Fig. 2; and "i Fig. 4 is a circuit diagram showing the punch selecting circuits. Y vThe punch chosen for illustrating .the invention isv of well known form and fullywdescribed in the copending application of J.T. m5 A i Schaat; Serial No. 731,980, iledAugust .14, 1924: (Patent No. 1,821,078), vA row of punches isiindicatedat 10,-one for each index point .position-of 4a Hollerith f card which may be controlled by controlling@keys-1 1. Theun l a Vhole for accommodating each punch when it isdepressed.l Record cards 14 .arefedrone at a timeby a suitable carriage between guide plate 12 and die plate 13 the movement ofthev carriage being-governed by escapement mechanism which feeds each column of the card successively beneath the punches and after a punching operation feeds it automatically to the neXt column.

The operation ofthe punching mechanism may be most clearly seen from Fig. 3. Each operating key 11 when depressed closes con- 'tacts 15 which are in circuit with a punch Hs'electing magnet 16. Energizatio'nv of'this lmagnet lattr'act'slit's'armature rocking a lever '18 about its pivotand depressing a bar 19. The bar 19'is provided with a slot'accom- Y modatingone arm of a bell'crank 20 Vwhose other 'armfijspivotedto an interposer bar 21.

On energization of the magnet 16 to lower .'bar 19 thej'in'terposer bar 21 movesl to the left in 'Figi Each interposer bar overlies a punch andjis provided with a notch 22 at itsiendwhich in normal position is directly .b'ene'athbail 23 but which when shifted by "so enerdizationfof lits magnet movesy to the left 'causinng the 'bail'23` to coact with the higher 'f'sur'fa'ce ofthe interposer 21. The movement of' any vinterposer 21` tothe left rocksa bail v 24which inturn'imoves a'hookrod 25 to the left thereby closing contacts indicated at 28. '-Th'eclosurejof these 'contactsresults in enervgi'zation of punch magnet'29 which'through suitable linkage 3.() rocks bail 23 counterclockwise. `AAny interposer which is -in nor- 4o Vmal retracted position willpresent 'its notch 422 `tothe bail lso that movement of the latter does not result inmovement of the interposer but if any interposer is moved to the left as shown inv Fig. 3, l

depresses Vit resulting in punching by its corresponding punch 10. f Y

f The circui for the punch selecting magnets is shown' in Fig; 4. linterposed between the key control contacts and the selecting magnets :16' are a plurality ofgroups of contacts 31 all operating'inunison. With the middle contactsof these groups in their left rhand ;position, eachrset of key contacts is connected the 1 contacts 15 are connected to the lselecting magnet; the 2 contacts to the 2`selecting magnea and so on. Vhen the movable contact of groupA 31 is shifted tothe right as shown in thedrawings, each pair of key operated contacts 15 is connected to the punch selecting magnet 16 corresponding to the complement of the number represented by the keys, that' is the 1 set of contacts 15 are connected to the number- 8 selecting magnet;Y the thismovement of the bail other mannersl or that if desired,'the select- 75V ing contacts could'resultin selective punching of single holesVv or combinations according contacts could result 1n' lselective Vpunchselecting magnets may-a lso b.e selected by members other than thekeys 1 1.' rI he wires 80 '32 1n Fig. 4 are connected to the number'keys offa typewriter-so .that `these .number keys 'may be operated instead ofV then punch keys V11 to select the different punches. Y

The `methodof shifting the contacts'u 313.85. is shown inv Fig..2. TheV machine is provided with a key 33 marked-.D (Fig.1),and a key-34 marked C. Depression of thekey 33Vv or debit key resultsin punching complements that is in shiftingthefcontacts31T to the posi- 'i90 tionl showninFig.l 4 while thefdepression of the key 34'called the credit vvkey results in shifting the contacts '31j .to' their alternative .position to 1 select true values for punching.

The operation of the debit and credit `keys 33 and' 34risfshown`in `Eig'.y l2.f.-lr.l`he bell crank 35 pivotedi atk 3S: carries an insulatingA member 39 which vcoacts withthe middle contacts Vof groups 31. Withy the bell crank ,in the `position shown'in Fig.'2 therighthand con- 3100 'tacts 31 are closed and the left ,hand contacts are open which is the positionfor selecting true valuesA for punching. vWhen therdebit key 33 is depressed-bell crank35 -is rocked counterclockwiser shiftingythe `middle con-5105 tacts 31 so that the left vpai'rsclose andthe right pairs open. When the bell crank is rocked in this-manner a piny 40 on key 34y engages a slot 41 in a memberl attached to bell crank 35 and latches thebell-crank in itsll counterclockwise position to hold right hand vcontacts-31 closed. In this positiontheicomplementary punches are selected for' punching. The contacts may be shifted b ack tonormal yposition by depressing the creditV key 34 ""-1-15 in which case the pin 40'is lowered out'of the Y notch 41 and a spring 42 returns bell crankf- 35 to a position shown inthe drawings again drectlyto its selectingmggnet 16, That is', :closing right hand contacts31.
